Explanation:
Detailed explanation-1: -A one-cell embryo (zygote) is “totipotent” in both senses; yet, some authors characterize tumors [1, 2] and stem cells [3, 4] as “totipotent, ‘’ based only on the second definition (ie, the ability of these cells to produce a wide range of cell types).
Detailed explanation-2: -Finally, totipotent stem cells can make all three embryonic germ layers and the extra-embryonic tissue. The only known indisputably totipotent cell is the zygote.
